SHEET WINDING AN D WRAPPING MACHINE Application filed May 9,

This invention relates to machines for winding lengths of sheet materialinto rolls and wrapping them with paper and then sealing, and has beenmore particularly de signed for handling roofing -;nater1al such asisformed of felt impregnated witlras' phalt or similar material, although1t-1s not restricted to such use.

Roofing materialof this nature is made in various thicknesses andwidths, and, as it is desirable to roll in each package materialsuilicient to cover definite areas of a roof, this invention providesmeans by which the roofing is automatically measured 5 01? in suchvarious lengths as may be desired. Means is also provided for slittingthe roofing into stri s of the widths desired. It is also desirable tomeasure off the wrapping paper to conform .to the various sizes ofcompleted roll, and mechanism for accomplishing this function has alsobeen provided. The material should be wound under the proper tension, itbeing evident that, as the roll, increases in size, the rate of rotationthereof for a given linear speed of the material decreases.-

Winding mechanism, conforming to these requirements, has been providedby this in rention.

fingers be which are rotated to wind the same, together with means forremoving these fingers when the roll is completed so that it Thesefingers are so constructed and actuated that, before a new roll is to bemade, they are presented in correct position to receive the roofingsheet. Sheet-guiding devices, which direct the sheet between the fingersbut which do not interfere with the subsequent winding, are also a partof this invention.

in order to ensure proper wrapping of the roll, one end of a sheet ofwrapping paper is wound into the roll just prior to its completion, theother end of the paper having glue applied thereto so that, bycontinuing the Winding operation after the completion of the roll ofroofing, the wrapping thereof and fastening of the wrap ping paper iseffected.

Referring to these drawings,1 and 2 indicate a pair of side frameportions carrying the mechanism for handling the roofing material, and 3and 4 indicate side frame portions superposed on the portions 1 and 2and carrying the wrapping paper holding and feeding mechanisms.

Roll winding mecizwnism.-As shown more particularly in Figures 1, 2 and3, positioned adjacent the frame portions 1 and 2 are a series ofpedestal blocks 5, 6 and 7. The pedestal 5 is preferably'in fixedrelation to the frame portion 1, but the pedestals Hand 2 are preferablyadjustably mounted relative to the machine toward and from the frameportion 2 to adjust for different widths of rolls. As the exact methodof mounting these pedestals for such adjustments is immaterial to thisinvention, no detail showing thereof has been made.

Referring to Figure 9, pedestal 5 carries at its upper end a bearing 8within which is journaled a hollow sleeve 9. Fixed to the sleeve 9 atone side of the bearing 8 is a second sleeve 10 terminating at its endopposite to the bearing 8 is a flange 11. A collar 12, fixed tothesleeve 9 adjacent the opposite face of the bearing 8, holds thesleeve 9 from axial movement in this hearing. Journaled on the sleeve 10adjacent the flange 11 is a gear 13 which is pressed against the flange11 by means of a collar 14: surrounding the sleeve and uiged axially ofthis sleeve by means of a series of springs shown at 15 surroundingguide pins 16 made fast in a ring 17. Ring 17 is held in position by asplit collar 18 internally threaded to engage the threaded extremity ofthe sleeve 10. A tightening; bolt 19 may be used to draw tother thesplit ends of the rin g 18 to hold he same in adjusted position. Ifdesired, "s may be interposed between the the gear 13 and the gear 13 arivets as 20 being shown e washers are made fast to the By thisconstruction, the .u irictional driving relation to vs 10 which in turnis keyed by the so the sleeve 9. The frame portion 1 bearing 22 inalinement with the bear- 8 receive the sleeve 9 adjacent the inwardly ofthe bearing 22, a collar 23 is made fast to the sleeve 9 and adjacentthereto is made fast a spool flange 2 1 having a cover plate 24'. Withinthe sleeve 9 is carried a block 25 into the end of which are screwed aplurality of winding fingers 26, preferably four being; employed whichprojithrough perforations in cover plate oe inner end of the block 25has fact there's the end of a shaft '27 this shaft oeconcentric with thesleeve 9 and projecting outwardly therethrough.

may slide axially of the sleeve 9. but are prevented from rotationrelative thereto by means of slot 9 in the sleeve within which rides apin 27'. The rack bar 31. however, is held from rotation within itsguideway.

Referring to Figure 10, it may be seen that cam block 33 has formedtherein a series of notches 35 terminating at the end adjacent the rackbar in outwardly flaring portions 36, thus forming a series of pointedteeth 37 projecting toward the end of the rack bar. Fixed to the bracket23 adjacent I the end of the sleeve 9 is an upstanding pin 38 havingjournaled thereon at its upper end roller 3.9,this roller being of adiameter to pass within the slots 35 of the cam block. thisconstruction, on movement has "fixed on its outer end a bracket of therack bar in a direction to retract the fingers 26, the cam block 33impinges against the roller which enters between the teeth 37 and guidesthe shaft 27 in order to position the fingers 26 angularly so that thespaces therebetween may be properly presented to receive the sheet ofrooting material, as will later be described.

In order to move the rack bar, a pinion 40, meshing with the teeththereof is carried by a vertically extending shaft 41 journaled at itsupper end in the hearing 30 and journaled at its lower end in a bearing42 supported adjacent the foot of the pedestal 5. Within the bearing 42,shaft 41 carries a pinion 43 which meshes with a rack bar 44: projectingtoward the center of the machine. The actuating mechanism for this rackbar 4 will be described later.

Pedestals 6 and 7 carry a mechanism in all respects similar to that justdescribed supported by frame member 1 and the pedestal 5 except that itis reversed end for end so that the fingers 26 for supporting the rollextend in the opposite direction. This construction is shown inelevation in Figure 3.

Roofing feeding and mittingmechamsm. Referring now to Figures 1, 2 and4, the frame member 1 at its forward end has an angular depression shownat and adja- 9 cent the upper end thereof the lower half of a shafthearing as at- 51. The upper half 52 of this hearing is formed as a.bracket member having at its upper end a vertical slotin which isslidab-ly mounted a bearing, 100 block 53. This block has journaledtherein a shaft 54 and a spring bears against the upper face of theblock 53 and against the under face of aretaining member 56. The shaft54 is journaled in a similar manner in 105 a bracket carried by theframe member 2 and has fixed thereon a pressure roll 57. This pressureroll is urged by the springs 55 into contact with the periphery ofameasuring roll carried by a shaft 61 journaled no in the bearing blocks51 and 52. The bearing block 52 has pivoted thereto at 62 a bracket 63,.Near the apex of the angular recess 50. this bearing bracket 63 hasjournale'd a shaft 61 which carries an idle tenl sion roller 65,'itbeing understood that a similar bracket 63 is carried by the frameportion 2 and carries similar bearing portions forthe various parts Onthe horizoutal lower face of the bracket 63 is journaled a shaft 66which may have fixed thereon one or more circular slitting knives, asshown at 67 Cooperating with these knives in shearing relation theretoare similar knives 68 carried by a shaft 69 journaled in the frameportions 1 and 2. The outer end of the bracket 63 has a pair of pedestaljaws for the slidable reception of a bearing block 70 urged downwardlytherein by a. spring 71 hearing between its upper face and a pedestalclosing block 72. This shaft carries an idler roll 73. Fixed outwardlyof this idler roll is a guide plate 74. The outer face of the bracket 63bears against the up per face of the frame portion 1 at and an eye-bolt76 pivotally mounted on the portion 1 on a pin 77, (see Figure carries anut 78 on its upper end which may be moved into engaging relation to thebracket 68. A similar construction is employed in connection with theframe 2 and allows the brackets 63 to be swung upwardly so that accessmay be had to the various rolls and the slitting knives for ease inthreading the material in the machine.

The strip of roofing, shown at A, passes downwardly between the guideplate 7-1 and the idler 73, and from thence past the slitting knives 67and 68 around the idler roll 65, around the measuring roll 60, beneath'the pressure roll 57, across the upper surface of a table 80 andbeneath a guide plate 81, and across the upper face of a shear.

block 82 to a supporting table 83 toward the winding mechanism. Pivotedat 84, between the frame portions 1 and 2, is a sheet guide 86, whichmay, if desired, be forined of a series of spaced links carrying attheir outer ends a roller 87.- The table 86 has a rearwardly projectinglug S8 to which is attached the end of a coiled spring 80 made fast at90, (see Figure 4,) to the machine frame. This spring normally holds thesheet guide 86 in the position shown in full lines in Figure 4 where-itfurnishes a continuation for the table 83 and over which the sheet A isguided between the fingers 26. As the material is wound, however, theroller 87 bears thereon and is moved downwardly, as shown in dottedlines, carrying the outer end of the table. to avoid interference withthe winding of the roll, this action being effected against the tensionof the spring 89. This construction not only serves to present the sheetA in position to pass between the fingers 26, but exerts pre sureon theoutside of the roll as it is formed, aiding in the closewinding thereof.This action is further aided by means of a pressure roll 91 carried byapair of arms 92 (see Figures 3 and 4) which are fixed to a shaft 93journaled above the fingers 26 and to which is fixed an arm 94: normallydrawn inwardly by a. spring 95 engaging over a hook 96 to the frame 1.

Cooperating with the shear block 82 is a cutting blade 100 fixed to aslide 101 guided in vertical slideways in the frame portions 1 and 2.The upper end'of these slideways are closed by retaining plates 102through which project vertically-extending posts 103 fixed at theirlower ends in the slide 101 and having a pair of check nuts 101 threadedon their upper ends. A cushioning spring 105 surrounds each post 103 andcushions the blow as the slide 101 descends, this descent beingaccomplished by gravity, as will later be explained.

For the purpose of actuating the mechanism so far described, thefollowing driving connections have been provided. Referring to Figures 1and 2, at is positioned a hearing bracket which carries journaledtherein a shaft 111, having afiixed thereto a driving belt pulley 112.Also fixed to the shaft 111 is a gear indicated at 113, meshing with agear 114 fixed to the main drive shaft 115. Above shaft 115 are threeshafts arranged in a horizontal plane atillG, 117, 118, which will bereferred to hereafter as the main cam shaft. the secondary cam shaft,and the clutch shaft respectively.

Referring more particularly to Figures 1 and 8, the frame portion 2carries a bracket 110 having journal bearings for a shaft which hasfixed thereon between the bearings a worm 121. 'This worm meshes with aworm gear journaled on the secondary cam shaft 117. At one end, shaft120 has a bevel gear 123 which meshes witha bevel gear 124 fixed to thedrive shaft 115. Outwardly of the frainc2, a gear 125 is fixed to theclutch shaft 118, and meshing therewith is a. pinion 126 (see Figure 1)carried by the drive shaft 115. It will thus be apparent that shaft 118will be driven continuously by the drive shaft 115, and that shaft 117may be driven through the worm 121 and the worm gear thereon when theworm gear-is in driving relation thereto, as will later be explained.

The shaft 116 is driven from the clutch shaft through change gears asfollows. Shaft 116 projects outwardly of the frame portion 1 and carrieson its end a gear 127 (Figures 1 and 2) which meshes with a gear 128carried by an arm 12$) pivoted or a shaft 130 journaled in the frameportioi 1. The arm 129 has an arcuate slot 131 concentric with thepivotal connection 130. A stud 132 passes through this slot and is fixedto the frame 1, and threaded on its outer end is a nut 133 which may bescrewed down against the arm 120 to hold it in position. Thisconstruction permits the use of various sizes of gears 127 by which thespeed of the shaft 116 may be varied, the arm 129 being adjusted tobring the gear 128 in mesh with the gear 127 whatever size of gear maybe used. The shaft 130 carries a gear 135 meshing with the gear 128. Asshown in dotted lines in Figures 2 and 4-, the shaft 130 also carries aspiral gear 136 meshing with a spiral gear 187 which is carried by avertical shaft having at its upper end a bevel gear 138. This gearmeshes with a bevel pinion 139 on the shaft 01 which carries themeasuring roll (30. A large sprocket wheel 140 is also carried by theshaft 61 and over this sprocket is passed a drive chain 141 whichengages a sprocket wheel 149; journalecl on the shaft 118. The shaft 61also carries a sprocket wheel 1 13 over which passes asprocket chain 14%engaging a sprocket wheel 145 fixed to the shaft 9 for rotating thesplitting knives 68. The winding mechanisms are actuated from the clutchshaft 118 as' follows: Arranged beneath the she 118 is avertically-extending shaft 146 (see Figures l and 8) which carries atits ier end a oevel gear 117 meshing with a r of bevel gears 148 and 149(see Figure et on the shaft 118. The lower it 1413 carries a bevel gear150 a similar gear 151 fixed to a shaft carries a pinion 1:33 in i 1.54and 155 ositioned above and er bar 1- being fixed to ioned, by whichmech- 2-6 are moved axially plaincd.

At oppositeends of this shaft are carried the snail cams 184 which are adapted toimpinge against posts as 185 fixed to the knife slide 101. In order toensure a free movement of the slide 101, opposite ends thereof areprovided with series of rack teeth 186 which mesh with a pair of spurgears, 187 carried at opposite ends of an equalizing shaft 188 journaledat its opposite ends in the frame portions 1 and 2.

The mechanism thus described is timed to obtain the following sequenceof operations, as will be more fully described later. The feed roll isturned to feed a length of roofing over the tables and 83 and betweenthe fingers 26 as shown in Figure 1. When the strip is in properposition between these winding the roofing in a roll, preferably oneroll being formed on each of the op posed series of fingers, the roofinghaving been split by the knives 67 and 68 on its passage thereto. 1V hensuflicient roofing has been wound on these lingers, in accordance withthe setting of the change gears above mentioned, the rotation of themeasuring roll 60 and the winding fingers 26 is stopped, and furtheraction of the machine causes the snail cams to allow the knife 100 todrop, thus severing the strips. This having been accomplished, rotationof the fingers again started to complete the winding of the roll. Whenthis has been completed, the rotation of the fingers is stopped and theyare then retracted axially from the rolls by the'action of the clutchmechanism '17 3 through which motion is imparted to the chine causes theroll fingers to return to their former position and stop, while themeasuring roll 60 is again actuated to feed the material in positionbetween these fingers for a repetition of the same cycle of operations.

Wrapping paper mecimnism.-5ust prior to the completion of the windingoperation a strip of wrapping paper is fed to the roll by mechanismwhich will now be described. Referring more particularly to Figures 1,8, 4, 5 and 6, the frame portions 3 and i carry, above the measuringroll, in sockets, a shaft 200 for supporting the wrapping paper roll orrolls. The paper is led up from the inner side of these rolls, over afeed roll 20% positioned near the upper part of the machine, and asshown more articularly in Figure 4 down through a guideway 202 having ashear blade 203 at its lower ed e, past a cooperating shear blade 204carried by the upper end of a rocking brackst 205, a clamping plate 206being positioned opposite the bracket 205 and cooperating The paper thenpasses over an abutment roll 207 arranged totake the pressure from aglue-applying roll 203, thence down in.

contact with a feeding belt 209 passing over I an upper pulley 210 and alower pulley 211,

a series of guide fingers 212 (see Figures 3, 4 and 6), being positionedin parallel re lat-ion to the feed belt to hold the paper in contactwith the latter. The feed belt and the fingers 212 act as a chute toguide the lower edge of the paper closely toward the rollof roofing. Inorder to impart a positive feed for the paper the feed roll 201 isdriven through a pair of meshing gears 213, 214 (see Figures f and 6)carried adjacent the frame member 2, gear 214 being carried on a shaftadjustably mounted in slots 215 in the frame portions 3 and 4. Thisallows gear-S214 of different sizes to be suhstitutedns desired in orderto determine the amount of paper to be fed. This gear 214 is driven froma s rocket wheel 216 carried by the same sha t by a chain 217 whichpasses about a sprocket wheel 217 'journaled on a shaft 218. A secondsprocket 219 fixed to this same shaft carries a chain 220 which passesdownwardly around a .sprocketwvheel 223 carried by the main cam shaft116-. As this shaft, as before described, is driven through a system ofchange gears, it is evident that the paper feed willbe subjected notonlyto the adjustment derived therefrom in conformity to the feed'of theroofing, but is also subject to further modification by the change gear214. r

In order to properly feed the paper as is passes over the feed roll 201,it is held pressed thereagainst by means of a pressure roll 224 carriedon a shaft 225 journaled in a pair of bell-crank arms 226 (see Figure6)., these bell-crank arms having out wardly extending portions 227 towhich may be attached weights as 228 (see Figures 1, 4 and 5).

The wrapping paper is cut into proper lengths by the knife 204 which iscarried by the rocking bracket 205 fixed to a shaft 229 projectingoutwardly of the frame 3 and having fixed at its outer end an arm 230.To the end of this arm is attached by a bolt and slot connection-at 231the upper end of. a link 232 which is pivoted at 233 to the knife slide101, it being thus evident that with each descent of the knife slide toout the roofing, knife 204 will also be actuated to cut off a section ofthe wrapping paper. The pressure plate 206 cooperating with the knifebracket 205 is normal 1y held in contact with the paper by means of aspring 234 fixed at one end to the frame' and engaging over an arm 235fixed to a rock shaft 236 which carries this plate.

The glueapplying 1:011 208 is-carried by a pair of arms 237 fixed to arock shaft 238 which carries at one end an arm 239 having a cam roll atits outer end in cooperative relation to a cam 240. This cam is carriedby a shaft 241 extending across the machine, and outwardly of the frameportion 4 this shaft carries a sprocket 242 over which passes a chain243 which leads downwardly to a similar sprocket wheel 244 carried onthe secondary cam shaft 117. The cam 240 7b is so formed that therotation thereof causes the glue-applying roll 208 to be moved at timesaway from the paper and into c0ntact with a. glue-applying roll 245dipping down below the surface of gluecontained in a receptacle 246. Theroll 245 is carried by a shaft 247 extending outwardly from thereceptacle and through a pair of bearings 248 (see Figure 0) at eitherend "thereof. Outwardly of the bearing 248 adjacent the 8 frame portion'3, the shaft"247carries a sprocket wheel 249 overjwliicli passes achain 250 which connects with a similar sn'ocket wheel 251 carried by'ashaft 252.

' utwardly of thev frame 3,sha ft 252 carries a belt wheel 253 whichmay.bedriven by a belt from any suitable source as a counter-shaft mountedabove the machine, This shaft 252 alsocarries the feed belt roll 2'10.The'abutment roll207 for the feed belt 3*? is similarly carried on ashaft '2 54 which projects outwardly-from the frame 4 and has fixed atits outer end abelt ungyesa; which may also be drivenfrom the over headcounter-shaft. f I f 10,

This mechanism is so timed. as to 'feeda" length of paper from therollcarried by shaft 200 in the path, as above described," during the feedof the roofing material As the roofing material is cut, the length of 0paper is out also and the upper end thereof is held between the camplate238 and the? rocking bracket 205. Thereuponthe glueapplying roll 208 ismoved into" contactwith the paper near its upper end and the 9 ring toFigure 7, the main cam shaft 116 '125 carrying the cam 179 is inposition to hold the clutch 178 in engagement with the worm 122, so thatthe secondary cam shaft 117 is connected for driving. The cam 174 onthis shaft is in such a position that the clutch .the mai on acts toagain throw clutch 178 into en- 170 is in engagement with the sprocketwheel 142 so that the measuring roll is connected in driving relationwith the clutch shaft 118, as above described. The clutches 171 and 172are out of engagement with the sprockets 160 and 161 and the clutchmechanism 173 is in mid position out of engagement with both bevel gears148 and 149, so that the winding mechanism is ldle. On actuation of themachine, the measuring roll is then driven from the clutch shaft 118 andthe paper feed is driven therefrom toward the fingers 26. The roofingmaterial then feeds in between the pairs of fingers 26 into the positionshown in Figure 4, whereupon the cam 175 on the secondary camshaftactuates the clutch 171 to rotate the fingers 26, as above described, ina counter clockwise direction as seen in Figure 4, thus starting to windup the roofing. Just after-the clutch 171 is thrown in, cam 179 on themain cam shaft acts to throw the clutch 178 out of engagement with the'worm 122, thus stopping the rotation of the secondary cam shaft,whereupon the cams 174, 175, 176 and 17 7 are idle. This condition ofthe mechanism continues until the main cam shaft 116 has made nearly acomplete revolution, the time thereof depending on the size of thechange gears used. Toward the completion -of this rotation of cam shaft116, the earn 179 theregagement with .the worm 122, thus again startingthe rotation of the secondary cam shaft 117. The cam 174 then acts tothrow clutch 170 out of engagement with thesprocket 142,-whichdiscontinues the rotation of the measuring roll, it having rotatedsulficiently to feed out the required length of roofing for the roll andpaper for wrapping it. At the same time that clutch l70is thrown out,clutch 171 is also dis connected from the sprocket 160 to discontinuethe rotation of the winding fingers 26. At this pointin the cycle ofoperations, the snailcams driven from the' secondary cam shaft 117 allowthe knife 100 to descend by gravity to sever the roofing materialagainst the edge 82, and at the same time the wrapping paper knife 204is actuated to sever the strip of wrapping paper. The rotation of thesecondary cam shaft 117 also actuates the glue roll, as beforedescribed, to apply glue to theupper portion of the wrapping paper. Assoon as this cutting of the strips and gluing of thewrapping paper hasbeen effected, the clutch 172 is thrown'into engagement with thesprocket 161, by the action of the cam 176 on the secondary cam shaft,to start the rotation of the winding fingers 26. The lower end of thewrapping paper, passed downwardly through the machine by means of thebelt 209, is presented to the roll by the time the second rotation shaftthen disengages the clutch 172 by the I I action of the cam 176, androtation of the winding fingers ceases. The cam 177 on the secondary camshaft now acts to throw the clutch mechanism 173 into driving engagementwith the gear 148, which acts through the horizontal bevel gear 147 toactuate the mechanism for retracting the winding fingers 26. The outerend of the roll being held by the spool flange 24, this motion of thefingers pulls them from within the roll, which thereupon falls from itsposition and may be received by any suitable conveyor, by which it maybe removed from the machine. In case the roofing is split in two by theknives 67 and 68, it is evident that a pair of rolls are wound andwrapped to throw the clutch 170 into engagement with the sprocket 142 tostart the measuring roll for a subsequent cycle of operations.

Having thus described an embodiment of this invention, it should beevident to those skilled in the art that many modifications and changesmight be made therein without departing from its spirit or scope asdefined by the appended claims.
